JTable hide and show columns

Question

I want to add some columns to a table (Swing JTable). Some of them will have a default size (e.g. 250), others will be hidden (so their size will be 0). I use this code:

Answer 1

try this something like this for example:

myTableModel = new DefaultTableModel();
myTableModel.setColumnIdentifiers(new Object[]{"ID", "Name"});
JTable myTable = new JTable(myTableModel);

// remember to save the references
TableColumn myTableColumn0 = guiLoteryNumbersTable.getColumnModel().getColumn(0);
TableColumn myTableColumn1 = guiLoteryNumbersTable.getColumnModel().getColumn(1);
//...

// remove temporary the column ("hide")
myTable.getColumnModel().removeColumn(myTableColumn1);

// then you restore that column when you need it ("show")
myTable.getColumnModel().addColumn(myTableColumn1);

That's the best way I know to hide a column.
